Curcumin is a flavonoid found in the rhizome of turmeric plant (Curcuma longa L.) and has recently attracted interest because it numerous biological functions therapeutic properties. In present study, we attempted to incorporate curcumin into medium-chain triglyceride (MCT) nanoemulsions (0.15 wt% curcumin, 10 MCT oil, emulsifiers) with various emulsifiers [polyoxyethylene (20) sorbitan monolaurate (Tween-20), monooleate (SM), soy lecithin (SL)]. The physicochemical properties including...
The effects of the purple-fleshed sweet potato extract (PFSPE) on oxidation stabilities a model oil-in-water emulsion prepared with enzymatically synthesized fish oil-soybean oil structured lipid (SL) versus physically blended (PBL) without modification were evaluated. anthocyanins in PFSPE analyzed and identified by HPLC-MS. fatty acid composition SL was similar to that PBL, except palmitic (1.48 PBL 9.61% SL) linoleic (62.47 49.58% SL). Peonidin 3-caffeoylsophoroside-5-glucoside,...
Abstract In this study, the stability of oil‐in‐water (O/W) emulsions prepared with structured lipid (SL) were evaluated in which SL was produced through lipase‐catalyzed interesterification between soybean oil and rice bran oil. After interesterification, major TAG species PLP (22.5 %), PLL/OOLn (21.8 LPL (16.1 LLS/PLO total amount tocopherol tocotrienol 20.9 mg/100 g SL. Sophorolipid used as an emulsifier for preparing SL‐based O/W emulsions, effect pH (pH 5.8, 7 7.2) on studied by...
Abstract To compare the oxidative stability between diacylglycerol (DAG) oil and conventional triacylglycerol (TAG) (that is, soybean oil), prepared stripped (SDO) (SSBO) were stored at 60 °C in dark for 144 h. During storage peroxide values (POVs), contents of aldehydes, unsaturated fatty acids measured to evaluate stabilities 2 oils. The results showed content C18:2, C18:3, total acid decreased faster DAG than oil, whereas rate C18:1 was similar Also, both constants ( K 1 ) obtained from...
ABSTRACT Until now few comparisons of nutritional compounds in premature green and mature yellow wheat have been reported. In this study, the contents amino acids, vitamins, mineral compounds, phytosterols, fatty acids as well proximate composition were investigated. Premature had lower protein content (12.0 g/100 g db) higher dietary fiber (19.3 than (13.6 14.3 db for fiber, respectively). Despite a small difference total significantly greater proportion essential acids: 16.1, 39.9, 32.7...
Abstract 4‐Vinylsyringol was produced by decarboxylation from sinapic acid. To evaluate the antioxidant activity of 4‐vinylsyringol, 500 ppm acid, or α‐tocopherol added to soybean oil and oxidation processes were monitored peroxide value (PV), thiobarbituric acid reactive substances (TBARS) assay, 1 H‐NMR spectroscopy. The results obtained PV TBARS indicated that containing 4‐vinylsyringol (SBO‐VS) showed highest oxidative stability. analysis also concurring results. After 19 days oxidation,...
In this study, two in vitro digestion models were employed to compare the rate of lipolysis soybean oil (SBO), pomegranate (PGO), a physical blend (PHY, 1:1 molar ratio SBO:PGO, w/w), and their enzymatically interesterified (IO). pH-stat model (emulsified oils with bile salts), PGO emulsion containing 74.7% conjugated form linolenic acid (CLn) showed significantly lower release free fatty (FFA) than other emulsions (p < 0.05). FFA rates droplet sizes between PHY IO emulsions, no significant...
Abstract Lecitase Ultra and 6 triacylglycerol lipases (lipases PS, M, AH, AY, R, AK) were immobilized on Amberlite XAD 7HP used to catalyze the acidolysis reaction between lecithin capric acid (C10:0) for comparison. The highest molar incorporation value (51.0 mol%) was observed Ultra. Further, selected catalyzing fatty acids with different chain lengths (C6:0, C8:0, C10:0, C12:0, C14:0). After reaction, free removed by SPE resultant called modified fraction 1 (MLF1). obtained C10:0 at 45 °C...
Caffeic acid was used to synthesize 4-vinylcatechol (4-VC) by thermal decarboxylation and prepare caffeic phenethyl ester (CAPE) esterification reaction. The identities of synthesized products were confirmed (1)H NMR. Antioxidative activities 4-VC CAPE compared with α-tocopherol BHT in stripped soybean oil at 60 °C under the dark. To evaluate degrees oxidation different concentrations combinations, peroxide value (PV) NMR performed. From results PV, formation primary (i.e., hydroperoxides)...
Abstract: The desired mix of alpha‐linolenic acid (ALA)‐enriched structured lipid (SL) and physically blended (PB) was prepared from grape seed oil perilla at a weight ratio 3:1. major triacylglycerol species (LnLnL) in PB drastically increased after interesterification (SL), 0.5% to 16.8%. After the reaction, total unsaturated fatty sn‐2 position decreased 98.83% 91.36% SL. reduction vitamin E compounds also observed. Compared with PB‐based emulsion, SL‐based emulsions showed oxidative...
The chemical characteristics of seed oils Asian ginseng (Panax C.A. Meyer) at different ages grown in Korea (3, 4 and 5-year old) China (5-year old), American quinquefoliu L., were compared. Total fatty acid composition showed a significantly higher oleic content (87.50%) than Korean (68.02～69.14%) Chinese (61.19%).

Abstract: Alpha‐linolenic acid (ALA) enriched structured lipid (SL) was produced by lipase‐catalyzed interesterification from perilla oil (PO) and corn (CO). The effects of different reaction conditions (substrate molar ratio [PO/CO 1:1 to 1:3], time [0 24 h], temperature [55 65 °C]) were studied. Lipozyme RM IM Rhizomucor miehei used as biocatalyst. We obtained 32.39% ALA in SL under the optimized (molar ratio—1:1 [PO:CO], temperature—60 °C, time—15 h). In SL, major triacylglycerol (TAG)...
알칼리 추출법을 이용하여 쌀귀리로부터 단백질을 추출하고 추출수율을 최적화하기 위한 농도 조건 및 침전 pH 조건을 반응표면분석을 통해 검토하였다. 추출수율은 추출용매인 농도가 증가할수록 그리고 4.9 부근에서 높은 경향을 보였으며, pH에 비하여 보다 큰 영향을 미치는 것으로 나타났다. 추출 공정으로 얻어진 귀리 단백질 농축물의 질소용해지수는 등전점 부근인 5에서 최소값을 나타내었고, 3 이하, 7 이상에서는 급격히 증가하였다. 공정의 최적화를 회귀분석 결과, 0.06 N, 4.7에서 최대 수율 85.89%로 예측되었으며 예측모델식과 실제 측정값을 비교하였을 때 유의적인 차이가 크게 나타나지 않아 설계된 실험모델식은 적합한 따라서 기존의 연구들은 이용한 시 농도와 pH가 각기 다름을 보였지만, 본 연구를 통하여 농축물 제조를 알칼리추출 최적 조건은 4.7인 확인되었다.
